/* ============================================================
   SWISS CLUSTER MENU — component styles
   Framework-free. Scoped under .sc-page so it won't collide
   with the rest of your project.

   Background is transparent — the component adapts to whatever
   page it is placed on.

   Theming: override the CSS variables in :root or on .sc-page.

   Responsive behaviour (self-contained — no page CSS needed):
     > 1100px        full horizontal row, tagline visible
     721px–1100px    horizontal row, tagline hidden (avoids an
                     ugly truncated "Advanced Thin F..." ellipsis)
     <= 720px        fully stacked: logo -> tagline -> Menu button
